Constant and SharedVariable are different subclass of Variable. So if you just want to know if an object is a Theano Variable, you can just call
isinstance(obj, theano.Variable) The variables related to random are sometimes subclass of SharedVariable (for the state) ( the random on the CPU that wrap numpy generator).
